The term for the biological study of animal life is "zoology." Zoology encompasses the study of various aspects of animal biology, including behavior, physiology, structure, evolution, and taxonomy. It is a sub-discipline of biology that aims to understand how animals interact with their environments and other organisms. Zoologists may focus on specific groups of animals, such as mammals, birds, reptiles, or insects, and conduct research in various settings, including laboratories, field studies, and conservation efforts. Zoology plays a crucial role in advancing our knowledge of biodiversity and informing wildlife conservation policies and practices.
